Differential effects of foraging strategies on carotenoid‐derived plumage color and individual quality in stripe‐tailed yellow finches

Journal of Avian Biology, Volume 2025, Issue 2, March 2025.
Carotenoid‐based plumage color is crucial in avian mate selection, often serving as an indicator of individual quality. To determine whether carotenoid‐derived color can be a sign of individual condition and if there is a relationship between an individual's condition and color production, it is necessary to identify how carotenoids are acquired by ...

Tree species controls over nitrogen and phosphorus cycling in a wet tropical forest

Ecological Monographs, Volume 95, Issue 1, February 2025.
Abstract Wet tropical forests play an important role in the global carbon (C) cycle, but given current rates of land‐use change, nitrogen (N) and phosphorus (P) limitation could reduce productivity in regenerating forests in this biome. Whereas the strong controls of climate and parent material over forest recovery are well known, the influence of ...

Non‐native invasive plants in tropical dry forests: a global review of presence, impacts, and management

Restoration Ecology, Volume 33, Issue 1, January 2025.
Tropical dry forests (TDF) are among the most‐threatened terrestrial ecosystems, experiencing ongoing conversion to agricultural fields, pasture, and human settlements. Human disturbances are often precursors to invasion of ecosystems by non‐native species, but research on invasion patterns in tropical ecosystems is sparse, and there is no ...

Allelopathic evidence in Brachiaria decumbens and its potential to invade the Brazilian Cerrados

Brazilian Archives of Biology and Technology, 2008
The aim of this study was to look for evidence of allelochemicals in B. decumbens, in parts of the plant from where they could easily be released to the environment.

Farming cattle in the tropics: Transnational science and industrializing pastures in Brazil

PLANTS, PEOPLE, PLANET, Volume 6, Issue 5, Page 1060-1069, September 2024.
Society is increasingly concerned over the environmental impact of diets. Much of this concern is over the environmentally destructive nature of meat production, especially beef and especially in the Amazon. This article aims to understand the production of beef in Brazil through the understudied perspective of forage grasses.

Impact of the invasive alien grass Melinis minutiflora at the savanna‐forest ecotone in the Brazilian Cerrado

Diversity and Distributions, 2004
ABSTRACTExotic grasses are a serious threat to biodiversity in the cerrado savannas of central Brazil. Of particular concern is the possible role they may have in impeding tree regeneration at gallery (riverine) forest edges and increasing fire intensity, thereby driving gallery forest retreat.

Airborne Volatiles from Melinis minutiflora P. Beauv., a Non-Host Plant of the Spotted Stem Borer [PDF]

Journal of Essential Oil Research, 2000
Abstract Airborne volatiles released by Melinis minutiflora P. Beauv., a non-host plant of the spotted stem borer, Chilo partellus (Swinhoe), were trapped from the live plant by air entrainment into porous polymer Porapak Q and analyzed by GC and GC/MS. The main hydrocarbons identified and confirmed by co-injection with authentic samples on two columns

Nitrogen acquisition and retention pathways in sustainable perennial bioenergy grass cropping systems

GCB Bioenergy, Volume 16, Issue 6, June 2024.
Perennial tall grasses sustain high biomass yield with minimal synthetic nitrogen (N) fertilizer, potentially by leveraging biological N fixation and nitrification inhibition. Enhancing these traits through research and breeding can further reduce their reliance on N fertilizer and thereby support more resilient and environmentally sustainable ...
